Fixed separations,
high-performance and compliant
A plasterboard partition (drywall) consists of a metal frame clad with plasterboard, with mineral wool insulation in the cavity. It is fixed, economical over long runs and offers excellent acoustic and fire performance.
CBI builds standard, acoustic and fire-rated EI30 / EI60 partitions, wall linings, service risers and casings, with neat finishes (taping, jointing, skimming) ready for painting.
It complements the demountable partition: it is chosen for permanent separations, wet rooms, risers and walls requiring a high fire resistance.
Acoustics
From 40 dB to over 60 dB (Rw) depending on the thickness, the number of boards and the decoupling of the frame.
Fire-rated
EI30, EI60 and beyond with special boards, for stairwells, corridors and separations between units, compliant with Swiss AEAI/VKF fire safety regulations.
Wet rooms
Moisture-resistant boards for bathrooms, kitchens and changing rooms, ready for tiling or suitable paint.
Finishes
Taping, jointing and skimming for a flat, ready-to-paint surface; protected corners and expansion joints.
Partitions, wall linings and casings
Dividing partitions
Separation of offices, hotel rooms, classrooms: single or double layer, acoustic insulation, heights of several metres with reinforced framing.
Fire-rated and security partitions
EI30 / EI60 walls, high-impact boards for circulation areas and schools, anti-intrusion or lead-lined boards for sensitive rooms.
Wall linings, risers and casings
Insulated lining of existing walls, vertical service risers, casings for columns and beams, boxing and recesses.
